The Red Devils were hosting the Ligue 1 side in the first leg of their last 32 clash in the Europa League and Ibrahimovic won a first-half free-kick in fortuitous circumstances.
The summer signing assumed control of set-piece duty and the 35-year-old fired a low shot under the wall which was deflected past Stephane Ruffier and into the net in the 15th minute.
Ibrahimovic’s free-kick was his 21st goal of the 2016-17 season in all competitions to help settle Manchester United before the veteran striker completed his hat-trick with two second-half goals.
Speaking to BT Sport, Scholes said:
“He is trying to hit it under the wall. We saw it the other night and Philippe Coutinho was sat the behind the wall trying to stop something like that.
“Fortunately it hasn’t happened. I question the goalkeeper. The ball went so slowly over the line. He just can’t get himself up.”
Manchester United will take on Blackburn Rovers in the FA Cup fifth round on Sunday afternoon before the Red Devils make the short trip to Manchester City in the derby at the Etihad Stadium in their next Premier League game.
The Red Devils are in sixth place in the Premier League table.
